Re-reading upthread, why was it necessary to consider A and D ends?
Presumably because they were converted from "handed" vehicles, and making them ambidextrous would be expensive? There are very few opportunities for LU trains to be turned round, and even fewer occasions when a specialist unit like this would need to couple to anything else anyway.
Sorry for ressurecting an old thread but I was wondering today if there have been any developments as to what’s to happen to the 4 DMs. I noticed there were some signs that said they were outside of the possession of (I assume) the depot today and the units are also looking increasingly shabby. I just hate to see them in such a sorry state 😢
